JACK APPARATUS FOR VEHICLES.

Specification of Letters Patent.

latcnted Sept. 2, 1913.

Application filed June 19, 1912. Serial No. 704,480.

To all lwlw/m, fit may concern.'

Be it known that I, Mox'raonn SinrsoN, a citizen of Great Britain, and residing at New York, in the county of New York and State oi New York, have .invented certain new and use'iul Improvements in .lack A pparatus for Vehicles, of which the following is a specification, suchl as will enable those skilled in the art to which it appcrtains to make and use the same. Y

This invention relates to jack apparatus ot devices for use in connection with vehicles, and particularly for use in connection with automobiles, and the object thereof is to provide an improved apparatus ot this class by means of which the vehicle may be instantly raised above the ground or suri'ace over which it is moving while in motion in order that said vehicle may be brought to a quick stop so as to prevent a collision or the striking of an object or person by the vehicle when in motion; a further object being to provide an apparatus of the class described, by means of which a vehicle of the class specified may be raised :from the ground in the case of the bursting or explosion of a tire so as to save the shoe oit' a tire, or the rim of a wheel, and to prevent possible injury to the occupants of the vehicle, and whereby a vehicle of the class specified, when standing still or in a garage, may be easily raised above the ground so as to relieve the tires of pressure occasioned by the weight of the vehicle.

rlhe invention is fully disclosed in the following specification of which the accompanying drawing forms a part, in which the separate parts of my invention are designatcdv by suitable reference characters in ea ch ofthe views, and in which Figure l 'is a diagrammatic side view oit' an automobile showing the axles in section and showing my improvement applied;-- fig. 2 a view similar to Fig. 1, but on an enlarged scale, and showing the operation of the jack to raise the vehicle;-Fig. 3 an end view of one member of the jack apparatus looking' in the direction of the arrow 3 ot' Fig. 2;-Fig. l a vertical section of said member of the jack apparatus on the line 4 t of Fig. 2;-Fig- 5 a view similar to Fig. l, but showing only one jackmember and showing a modification; Fig'. 6 a partial section on the line 6-*6 of Fig. 5, and on an enlarged scale, and ;--Fig. 7 a section on the line 7-7 ot Fig.

In the accompanying drawing, Fig. l, I have indicated in outline the body of an automobile, and I have shown the Alront axle o and the rear axle in :full lines, and said rear axle b is inclosed in a tube or sleeve b2 in which it is free to turn, and my improved apparatus, when used for the purpose specilied as shown in the accompanying drawing, is preferably crmiposed of four separate similar parts c two of which are suspended ii'rom each axle and on the inner sides of the wheels thereof, the rear parts of the apparatus being suspended from the sleeve b2 through which the rear axle passes and to which they are secured.

Each of the parts c consists of a strong rectangular .frame composed of a top member c, side members c and c4 and a bottom member ci'. The top member c2, in the form of construction shown is composed oi. two parts, the inner part c thereof heilig provided with a deep longitmlinal groove c7, and the bottom member c, in the Ylorm oit' construction shown, is composed ot two parallel side members o8.

rlhe side members c3 and c4 of the frame are provided in the lower end portions thereof with vertical slots c and mounted therein is a vertically movable 'horizontal bar (l having end members (l2 movable in the slots c, and said bar Z is provided in the top thereof:l with a groove (Z3 and on the bottom thereotl with downwardly directed ears or hangers al* in which are mounted rollers (Z5.

Mounted between the top members cD of the jack-:frame and the bar J are two pairs of toggle levers c each of which consists of two members pivoted together at c2, and the (mrresponding menibcrs ot each pair of toggle levers are pivoted together at one end, as shown at e and c", and said toggle lever meml'iers are provided at their other ends with anti-friction rollers c5 movable in the groove o7 in the top member of the jack- 't`rame, and rollers e movable in the groove Z3 in the bar d.

The lower end portions of the toggle lever members :7 are connected by a horizontal link device f pivoted thereto, and which consists of two separate parts of similar length pivoted together at fi', and pi\'oted to the side member c" of the jack-iframe is another linli device g which is also pivoted at fl and 'which projects beyond the pivotal point at f, and is provided with a short link device h, and pivoted to the side member c4 of the jack-frame is a crank lever 2'? the longer arm 2 of which is pivoted to the link device 71 and the shorter arm i ot which is connected with a crank rod y'.

As hereinbefore stated two of the jack devices, or jack-frame devices c are used in connection with each axle, and said jack devices are used in pairs at the opposite sides of the vehicle or on the opposite end portions of the axles, and the position of the said jack devices on the front axle is the reverse of the position olB said jack devices on the rear axle, and the chassis or truck trame is provided on its opposite sides and forwardly of the seat of the operator with hangers c which support a transverse shaft m to one end of which is secured a lever n, and the crank rod y' of the corresponding jack device on the rear axle is pivoted to the said lever above the shaft k, as shown at 7'2, While the crank rod j of the corresponding jack device on the front axle is connected with a backwardly directed arm of the lever n at the lower end thereof, as shown at js.

The normal position of the separate parts,

' or separate jack devices, or frames, 1s that shown in Fig. 1, in which the vertically movable bars al in the separate jack devices or frames are supported above the bottom-oi said frames, and the bottoms of said frames supported at a predetermined point above the ground, or the road over which the vehicle moves, and with this construction it willbe apparent that when theV lever fn, is moved backwardly in the direction ot the arrow X the crank levers i of the corresponding jack devices at both sides of the vehicles will operate the toggle levers e to depress the vertically\zmovable ,bars al in the jack `iframes or devices c, as shown in Fig. 2, and

this operation will raise thev vehicle bodily,

-as indicated in dotted lines in said figure,

and the ,weight thereof will rest on the rollers d5 supported by the bar d, and this operation will bring the vehicle to an immediate stop, orapproximately so, the weight .of the vehicle being supported on the said rollers instead of onithe wheels which are indicated atO. @t course, the transference of the weight otl the`vehicle from the wheels.

thereof to the rollers Z4 does not operate to absolutely stopthe vehicle, butl thefforward movement of 'the vehicle would be instantly reduced'l to a large extent and the force of said movement would be reduced tol a minimum, and the vehicle would be quickly brought to a full stop. f

In Figs. 5 to 7 inclusive, I have shown a modification of the construction of the `iack members in which a vertical plate pis 'secured centrally to the outside of 'the jack frame and to the top frame member c and one of the bottom frame members 08 from :invasores which the plate p is separated by spacing blocks p2, and said plate p is provided with a `vertical slot p3 and mounted thereon, is a slide mand the pivot pin f2 which connects the link members f passes through the slot p3 and the link device g is provided with .a longitudinal slot g2 through which the pin f2 passes. With this construction the operation ot the separate jack memberswill be the same as with the construction yshown in Figs. l, 2, 3 and 4, but the parts p and r serve as a brace to strengthen the toggle levers and link members, and to hold the same in )roper position under all circumstances.

he use of my improvement in connection with high speed vehicles of the automobile type and the use thereof, in case ot-the bursting of a tire, will be apparent, as the vehicle may be quickly brought to a stop in order that the tire may be replaced, or a new tire substituted, and injury to the rim ot the wheel may thus be prevented, and when the vehicle is not in use the jack apparatus may be employed for supporting the weight thereot on the rollers d5 and thus relieve the tires from the constant pressure at one point thereof occasioned by the weight ci' the vehicle, and in cases when the vehicle is in use, as for instance, in the case ot a possible collision the jack apparatus may be employed ab for causing the vehicle to stop at the earliest possible instant.

My invention is not limited to the exact details of the j ack apparatus or the separate parts thereof herein shown and described, and various changes therein and modifications thereof'may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrilicing its advantages, and I reserve the right to make all such alterations therein as fairly come within the scope ot the invention.

Having fully described my invention what I claim as new and desire to secure by Iletters Patent is i l. In a jack device of the class described, a rectangular main frame composed of top, bottomvand side members, a vertically movable horizontal bar mounted in thebottom. portion of said trame and provided with suspended rollers, toggle lever devices mounted between the top member of the main frame and said bar and having rollers operating in connection therewith, and means for operating said toggle lever devices so as to depress the rollers suspended by said bar below the main frame and lock the same in a depressed posit-ion.

'2. In a jack device of the class'. described, a rectangular frame composed of to bot-` tom and side members, the top meno. er being provided in the bottom thereof with a longitudinal groove, and the bottom member being composed of two parallel parts, and the side members being provided with verllt@ tical slots, :L vertically movable horizontal bar mounted in said frame and the ends of which operate in said slots, said bar being provided in the top thereof with a groove 5 and :1t the bottom thereof with suspended rollers, toggle lever devices mounted between the top member of the main frame and Suid bar and provided with rollers movable in the grooves in said member and ber, said 10 toggle lever devices being ivotnlly oonneoted, and means for operatmg seid toggle lever devices to depress said bar, and the rollers connected therewith below the mam frame. g

In testimony that I claim the foregomg es 15 my invention I have signed my name 1n presence of the subscribing witnesses thls 18th dey of June 1912.
